Dialog Box
A dialog box is a window that appears in order to collect information from the user. When the user has filled
in the necessary information, the dialog box disappears.
DIN Rail
Deutsche Industrie Norm Rail
DLL
In Microsoft® Windows®, a Dynamic Link Library contains a library of machine-language procedures that
can be linked to programs as needed at run time.
Downloading
The transfer of a complete set of parameters from the computer to a Epsilon EP-P drive.
Drive
Servo drive or amplifier.
EEPROM
An EEPROM chip is an Electrically Erasable Programmable Read-Only Memory; that is, its contents can
be both recorded and erased by electrical signals, but they do not go blank when power is removed.
EMC
Electromagnetic Compatibility. The relative immunity of a drive to the effects of electromagnetic fields.
EMI - Electro-Magnetic Interference
EMI is noise which, when coupled into sensitive electronic circuits, may cause problems.
Firmware
The term firmware refers to software (i.e., computer programs) that are stored in some fixed form, such as
read-only memory (ROM).
Flash
Another type of EEPROM.
Flash File
In the Epsilon EP-P drive, this file loads the firmware into the drive. Flash files can field upgrade the
firmware.
Global Where Am I
PowerTools feature that indicates which line of which user program is executing.
Home Routine
The home provides motion in applications in which the axis must precisely align with some part of a
machine.
Hysteresis
For a system with an analog input, the output tends to maintain its current value until the input level changes
past the point that set the current output value. The difference in response of a system to an increasing input
signal versus a decreasing input signal.
I/O
Input/Output. The reception and transmission of information between control devices. In modern control
systems, I/O has two distinct forms: switches, relays, etc., which are in either an on or off state, or analog
signals that are continuous in nature generally depicting values for speed, temperature, flow, etc.
